True enough. While I've seen a yellow in person, I've never seen a blue (only in pictures). I hadn't thought of that

, it's funny that it never crossed my mind when I have a hard enough time getting good pics in my own tank (under 14Ks).
What shade of blue would you describe your assessor as, Leah? I'm sort of curious now 'cause I sort of want a blue fish and would like to avoid any of the blue damsels (which get too big for nano's anyhow).
